I’d notice since few months, the SMS aren’t popping up by themselves anymore the UCP, nether updated when a new one get in. I’d need to close the conversation by pressing the “X” and to reopen it to see new messages with a thread.
How to make the thread popping up by itself and the new messages appearing by themselves within a thread without having the need to closing it and reopening it all the time to see if a new message get in?
I would open a bug report. This is done through polling and someone may have broken that in the module. It is technically commercial support because I am guessing you are using sipstation but I think bugs for that are handled with the big tracker
I just add more RAM to the VM hosting FreePBX to see if this was the cause, in the event if of the issue was caused by something else, I will open a bug report.
